To all whom it 'may concern: A

'Be itltnown that l, Sims W. Einem?, a

.citizen ot the United States of America, re-

the tollowing'is :t specification, reference being had therein to the accompanying drewing.

'i his invention relates to locomotive headlights, end its object is to provide improved 'the rays otk light are projected :iway

-menns for automatically edjusting'the headlightreiector when the locomotive is rounding e curve to direct the rirys et light along the center ci' the reilvvny "trecln As is Well known the inner rail ot e track` et e curve is lower than the outer reihend if ythe headlight meinteius its normal position es the locomotive posses around e curve,

the tinck;- ''lhe present invention aims to evoifl'A nis objection to the ordinary rigidly supported headlight, nucl it consists in the novel nie'ei'is hereinafter described or automatically ntliusting the headlight and causing it to iollow the leterel tilting movement ot the locomotive at curves, and thus insure u pr jection of the light reys along the cen.- ter ot the trncl; when rounding curves es iveli when traveling along e straightaway course.

in the accompanying drawing which forms e' portion o epplicetion, Figure l is n. ont elevation in which e rond-ioctl, locomotive wheels and axles, enel e boiler equipped with, improved efljusting mechanism are conventionally and iegreniznaticelly representen, Fig. .3 is e.

Fig. is e vertical cross sectional view of the heafilight. tional 'view of the seme.

The housing -2 which preferablycon'sists of'ofsqimre lloot( open et its iront side, issuitablysecured upon the ,n'nd totheA rear Well of the said housing'is pivoted :i pendulum 5, forked or biturceted Iet its upper end and provided4 at its lower end Weight 7. v

`. lrojecting from opposite pendulum 5 :it its pivotal Apoint `aieearxns 8 in horizontal alinement with eecli other, enel each'lprovidefl at its outer enilwith-.e Weight 9, said weights serving encounter-balances to meint-aiu the pendulum invertical position when the locomotive is traveling on a straight track, und to restorethe pendulum to e perpendicular position after it has been tilted from such .position .by its Weight 7.

Projecting rearward trom tlieupper pivot ot the relectbr is a. horizontal erm l() the rear end of which is received in the fork 6 oi the pendulum; From this construction, it is apparent that the retiector is restrained from tilting, and is capable oi swinging' upon a horizontal plane, being propelled hy the oscillations of' the pendulum.

The utility and operation ot' ing mechanism As long e straight course the pendulum will be maintained in perpendicular position by the counter-balance Weights 9, anti the headlight relectorwill remain in theposition shown by; the full lines on lfig.` 3. When however, the ioc'omotive strikes ,e curve Where the inner ruil is lower then the outer rail as shown in Fig. l, thelpendulumwill swing upon its pivotal' support enti through the intermediecy ofthe upper end et seid penclulurn and the rearwerdl extendinf erin l0 the relector will be tilted laterally es illustrated by the dotted lines in Fig.. and thus the rays of light will followl the path the adjustill be readily understood.

with i e lonllv Sides of the esoas the locointive is traveling upon ot the curve ot the track, and; be directed .relation to the arc of e circle by the employment ot the improved automatic adjusting mechanism. V 1

lt will be obvious that es soon. as the locomotive passes the curve and reaches e i level track the pendulum returnsm `its perpeiuiieuiar posit-ion which restores the re iieotor to its norma. position.

Haring uily described my invention Whit oiuim and desire to Secure by Letters Patent isz 1 The combination in au attachment 'for b eadiights, of e' verticaiiy-pivoted conical ,relee`tor, elrearwardly-extending erm earried thereby, e pentiuiumorm Weighted at its lower end and having an upwardly-extending arm forked to receive said rear- Verdly-exteudixig arm, and Weighted-arms carried by and projecting in opposite directions from the pendulum-firm at the pivotal point. of the letter.
